I stopped shopping at Amazon because their fulfillment started to suck. And I found they kept their dates 25/100.

Most recently I ordered 10 items on September 18th (I had a gift card). All prime eligible. The first arrived on sep 20, the 4 on sep 28, 5 on sep 28, and the last is scheduled for Friday.

I didn’t get any estimates until after purchase.

Amazon is no longer good. They are coasting on their customer base and are slowing ratcheting up prices and squeezing their costs (keeping all their gains).

I've noticed this lately in coastal California of all places. I needed batteries by Sunday morning, was ordering on a Thursday. Plenty of 1 or 2-day options when searching and adding to cart, then when it came time for checkout... none of the 5 options I tried could be delivered in 2 days!

It seemed the interface was designed to hide the true delivery estimate in the last step and trick me into thinking the item would arrive on time.

If they are not going to tell me the day it is going to arrive, I am not buying. Thats the "prime" reason for using Amazon these days.

when I check out there is usually a button that says "as fast as possible" or "fewer delivery days" or "slower delivery for discount"

It depends on the country. For the last few months here in Germany Amazon has been having major shipping issues
